Abstract: SAFETY COVER FOR ROTARY HEAD ELECTROSTATIC SPRAY COATING SYSTEMS Abstract of the Disclosure A safety cover for rotary head electrostatic spray coating systems, of the type to which a rapid rotation is imparted to a rotary spray head and a jet of coating material to be sprayed directed thereagainst for discharge from a peripheral edge of the head in a spray, is characterized by a cover movable between positions over and around the head and remote from the head, and a mechanism for moving the cover. When positioned over the head, the cover protects nearby personnel against accidental injury resulting from contact with the rapidly rotating head, and at the same time serves as a receptacle for receiving and containing solvent and residual coating material discharged from the head when the same is cleaned, as for example during color changes when coating materials of different colors are sprayed.

Abstract: Abstract Apparatus and methods are provided for installing an underwater anchor system including a plurality of separate anchors for a tension leg platform.  A cluster of tethering elements is connected between the tension leg platform and each of the separate anchors.  Each anchor assembly includes a primary anchor which is first located approximately in a desired position upon the ocean floor. This position includes a lateral location and/or an angular orientation about a vertical axis.  Then the position of the primary anchor is ascertained and compared to a desired position of the main anchor.  The main anchor is designed to be lowered into engagement with the primary anchor.  A relative position determining structure is interconnected between the primary and main anchors for varying the relative position of the main anchor relative to the primary anchor to correct for any difference between the ascertained final position of the primary anchor and the desired position of the main anchor. This relative position determining structure is adjusted as necessary.  Then the main anchor is lowered into engagement with the primary anchor so that a location and final angular orientation of the main anchor is determined by the relative position determining structure upon engagement of the main anchor with the primary anchor.

Abstract: ABSTRACT A channel selector comprises a programmable frequency-divider in which frequency-division ratio data available for deriving a desired local oscillation frequency according to the PLL technique are set, and a controller responsive to external control signals for producing fine tuning data to vary the frequency-division ratio data and varying the frequency-division ratio data according to the fine tuning data.  The fine tuning data consist of up/ down data for indicating whether the frequency-division ratio data is to be increased or decreased and quantitative data representing the quantity to be varied.  The fine tuning data are stored in a memory device.  If the channel for which fine tuning data were produced is again selected, the controller reads out the frequency-division ratio data corresponding to that channel which have been preliminarily stored in the memory device, and at the same time reads out the fine tuning data corresponding to that channel from the memory device. The controller varies the read frequency-division ratio data according to the contents of the read fine tuning data, that is, the up/down data and the quantitative data, and then sets the varied new frequency-division ratio data in the programmable frequency-divider.  Accordingly, the frequency-division ratio data derived as a result of the manual fine tuning operation carried out for a transmission frequency having a large frequency deviation, can be again set in the programmable frequency-divider without necessitating any manual operation by a TV viewer, when the same channel has been again selected to be received.

Abstract: T I T L E     A METHOD OF RENDERING LIGNIN SEPARABLE FROM CELLULOSE AND         HEMICELLULOSE AND THE PRODUCT SO PRODUCED     I N V E N T O R     Edward A. De Long ABSTRACT OF DISCLOSURE                 In the process for rendering lignin in lignocellulosic material separable from the cellulose and hemicellulose wherein the lignocellulosic material is packed in a divided form in a pressure vessel which is rapidly filled with steam at a pressure of at least 500 psi to heat the lignocellulosic material to an extrudable condition at a tempera-ture in the range 185 to 240°C in less than 60 seconds, followed by imme-diately extruding the lignocellulosic material to atmosphere, it has been found that the production of toxic components can be minimized by gently venting the pressure vessel to atmosphere to reduce the steam pressure to between of the order of 200 psi and of the order of 450 psi as soon as the extrudable condition is reached.  The lignocellulosic material is then extruded instantly to atmosphere immediately after the venting step.

Abstract: Inventors:     Theron C. Moss, Earl Boring and Jerry Hjellum Title:         "Extension Handle for Dust Mops and The Like"     ABSTRACT OF THE DISCLOSURE Extension handle consists of a pair of telescoping handle parts made out of relatively thin-walled plastic tubing. A protrusion on the outer wall of the inner tubular member, formed as by inserting a pop rivet therethrough, frictionally engages the inner wall of the outer tubular member to provide some drag or resistance to axial movement of the tubular members relative to each other. The outer tubular member, being made of relatively thin-walled plastic tubing, will deform more or less according to the amount of interference between the rivet and inner wall of the outer tubular member. A rigid metal or plastic ring at the inner end of the outer tubular member acts as an abutment or stop for the protrusion on the inner tubular member thus preventing the telescoping handle parts from being completely pulled apart.

Abstract: ABSTRACT OF THE DISCLOSURE      The method and apparatus sucks the entire combustion air volume in laterally with respect to the direction of flow of the air current with the help of the impulse of a fuel gas jet out of the air current into a mixing pipe and the formation of a differential pressure between the mixing pipe input and the waste gas output into the air current is prevented with the help of current guidance sheet metal pieces.   The burner is arranged in a shaft-like housing, the fuel gas nozzle and the lower part of mixing pipe are surrounded by a pot-shaped current guidance sheet metal piece.  A cylindrical current guidance sheet metal piece adjoins  the  cooled burner plate.  The burner which, for example, can be used in dryers, for heating room air with so-called make-up air units and in gas water heaters, operates completely independently of the air flowing around it in a wide heat load range, without any change in the air coefficient.  Because of the super-stoichiometric premixing of the burning gas with the air, the NOx content of the waste gas is extraordinarily small.

Abstract: PNEUMATIC METHOD AND APPARATUS    FOR CIRCULATING LIQUIDS                       Abstract A pneumatic method and apparatus for causing the rapid recirculation of a liquid between a plurality of containers 10, 11 by adjusting the pressure of a gas exerted within each of said containers to superatmospheric, atmospheric and sub-atmospheric pressures, thereby avoiding the passing of the liquid through a mechanical flow-inducing pump.  The containers 10, 11 are connected to each other by means of a liquid circu-lation system comprising a circulation conduit which includes a work station.  A filled first container 10 is subjected to superatmospheric pressure to force the liquid into the circula-tion system while a second empty container 11 is subjected to subatmospheric pressure to suck the liquid from the circulation system.  After each container is empty and before it is sub-jected to subatmospheric pressure, for refilling purposes, it is exposed to atmospheric pressure to release the elevated pressure therefrom.  The circulation system preferably incorpo-rates a bypass conduit 46 including a liquid replenishment tank 38 and/or means 39 for adjusting the temperature of the liquid.

The delaying means includes a tapped shift register, and also produces an unweighted version of the comb filter output signal delayed by an amount of time which is equal to at least half of the delay of the shift register.  Weighting means are coupled to the taps of the shift register and weight signals passing through it.  One of the luminance and chrominance information signals is produced by means coupled to the weighting means and cooperating with the shift register.
